Do unconditional branches, such as
goto instructions cause control hazards? If so, why?
I am wondering because if unconditional branches did cause control hazards, that is like saying if
A were the
jump foo instruction and another instruction
B was the first one under
B would have a control dependency on
A. While this is technically true, I don't see how this would cause a hazard in a pipeline since we know with 100% certainly that
B will be executed since an unconditional
A preceded it.
